OpenBSD's Packet Filter Gains OS Fingerprinting

Posted by CowboyNeal on from the no-more-amigas-on-my-networks dept.

basilpronoun writes "The PF packet filter / firewall that comes with OpenBSD has just been improved to allow firewalling decisions to take place based not only on the source of a connection, but the operating system of that source. There are both good and evil applications, not the least of which is blocking the spam from infected Windows machines."

    Now where did I put that openBSD box?
